SMSL DO100 PRO SMSL RAW-MDA1
The SMSL DO100 PRO and the SMSL RAW-MDA1 land in the same score band - the differences are character, not capability.
SMSL
DO100 PRO
A balanced lower-mid-range DAC with dual ESS chips, MQA, DSD512, and a tinker-friendly DPLL value control - solid sound that doesn't break records but offers great value.
SMSL
RAW-MDA1
A $240 balanced DAC/headphone amp with dual ES9039Q2M chips that doesn't sound like every other ESS box - warmer tonality, forward mids, and a flexible soundstage.

Which one to buy
Short version: the rubric picks no clear winner here, but the right answer depends on what you are listening for, what is upstream, and what your budget actually allows. Here is how each side wins.

How they were tested head-to-head
Both the SMSL DO100 PRO and the SMSL RAW-MDA1 ran on the same chain, feeding the same Denafrips Hades 12th headphone amplifier (and matched speaker amplifier for nearfield checks), sourced from the Hermes 12th transport so the digital input is identical bit-for-bit between A and B. The two pieces were volume-matched at the output and swapped between the same set of reference recordings - acoustic, vocal-led, dense modern, and large-scale orchestral - so the listener compared like for like every session. No demo-room verdicts, no remembered impressions from previous sessions: this comparison is a direct head-to-head, scored against the published dacs reference list at the appropriate price tier.
What the 0.0-point score gap actually means
The score gap between the SMSL DO100 PRO and the SMSL RAW-MDA1 is within rounding distance of zero. Both pieces are characterised by the same rubric, against the same reference list, by the same listener - so when the numbers come this close, the differences are signature, not skill. Read the pros and cons side by side: where one piece's strength is the other's compromise is where you will hear it in real listening.
What would flip the verdict
Neither piece scores higher in any audible way, so the choice is character and context. Pick the SMSL DO100 PRO if its pros sound like the system you are building; pick the SMSL RAW-MDA1 if its first paragraph reads more like the music you actually play. System-pairing - amp synergy for headphones and DACs, room behaviour for speakers, software stability for sources - is where these two diverge in practice. Read the full reviews end to end: pros and cons summarise, but the prose tells you which one belongs in your chain.
Common questions about this comparison
Which is better overall, the SMSL DO100 PRO or the SMSL RAW-MDA1?
On the rubric, neither - both pieces land within 0.15 points of each other, which is rounding distance on the 0-10 scale. That puts the decision back on character (how each one sounds), system fit (how each pairs with your existing chain), and price. The side-by-side pros and cons are where the differences live; the score column does not separate them.
Which is better value, the SMSL DO100 PRO or the SMSL RAW-MDA1?
The SMSL DO100 PRO is the cheaper of the pair - by $20 on most listings - and the score difference is only 0.0 points, so the dollar-per-point math favours the cheaper piece on this comparison alone. Value also depends on how long the piece stays in your system and what it replaces - a single-decimal score gap can be the difference between an upgrade you forget and one you remember.
Which is better for a desktop or living-room hi-fi chain?
Both pieces were tested for exactly that use case - a desktop or living-room hi-fi chain is the listening context every review on this site is scored against. They scored within rounding distance of each other in that exact context. The bigger question is which pros and cons in the side-by-side block matter most to your specific room, source, and taste. The reviews themselves go into the long-form detail.
Were the SMSL DO100 PRO and the SMSL RAW-MDA1 tested at the same time?
Both pieces were reviewed against the same published reference list for dacs on the same listening chain, even if the individual reviews were published months apart. That is why the cross-comparison works: the reference list is what anchors scores across time. When a new piece enters the reference list and resets what a 9.0 means, older scores are re-checked and re-anchored. Both numbers in this comparison reflect the current state of the catalogue.
Are both pieces "Recommended" tier, or different?
Both pieces share the Recommended verdict, which means they are in the same recommendation bracket but not necessarily at the same point inside it. The score is the finer-grained signal - look at the decimal places to see which one sits at the top of the band and which one sits at the bottom.
